Definitions

  • This invention relates to the molding of complex parts made of composite material, and utilizing a plurality of conformable cauls which cooperate to form one of the molds involved in the fabrication process and upon which the composite material is individually laid up and co-cured during the molding process.
  • simple parts could be molded by laying up the prepreg composite material selectively in a female mold, and then positioning the male mold within the female mold to apply pressure to the laid-up composite material, then placing the mold so assembled in an autoclave and curing the composite material under both heat and pressure.
  • This early method produced a single, simple composite part whose outer periphery is defined by the contours of the female mold, and whose inner periphery is defined by the contours of the male mold.
  • the composite material could as well have been laid up on the male mold in this early prior art process.
  • a vacuum bag replaced one of the molds, usually the male mold, and when under vacuum, produced pressure on the prepreg laid-up composite material in the female mold to cause it to closely conform to the shape of the female mold, and, i.e., to debulk the composite material, during the curing process in the autoclave where heat and more pressure are used.
  • an object of this invention to teach a molding process which is capable of producing a part made of composite material, and having a plurality of panels oriented in diverse angular relationship and wherein one of the molds used in the molding process comprises a plurality of conformable cauls which cooperate to form one of the molds during the molding process.
  • one of the mold parts comprises a plurality of conformable cauls, which have been fabricated utilizing a model formed to their shape, and which conformable cauls are fabricated to produce overlapping planes so that the cauls can follow the contour of the molds at mold corners when pressurized during the curing process.
  • FIG. 1 is a prospective showing of a composite part of the type which can be fabricated utilizing our invention.
  • FIG. 2 is a showing of the female mold used in the molding process taught herein.
  • FIG. 4 is a showing of our female mold with prepreg plies of composite material shown laid up continuously throughout the dimension of the mold.
  • FIG. 6 is a brief diagrammatical illustration of the female mold, including cauls, within a vacuum bag preparatory to being put in an autoclave.
  • co-curing means the simultaneous curing of a composite part and its details, or the simultaneous curing of two or more composite parts, with or without details.
  • the composite part to be fabricated 10 is a rectangular structure with a central partition or transverse bulkhead 12 and consisting of end panels 14 and 16, base panels 18 and 20, side members 22, 24, 26 and 28, each of which is made of composite material and fabricated so that in the bonding process, the individual panels are laid up and eventually co-cured to form a one-piece composite part shown as item 10 in FIG. 1.
  • the side panels include strengthening beads, such as 30 and 32, the end panels 14 and 16, the floor panels 18 and 20, and the transverse bulkhead 12 include NOMEX® (trademark of E. I. du Pont) core strengthening members 34, 35 and 36.
  • NOMEX® trademark of E. I. du Pont
  • These strengthening beads and cores, as well as thermoplastic bonding substrate 37, are all for the purpose of strengthening the final product 10.
  • Part 10 also includes retainer flange 38, which will eventually be used to connect composite part 10 to the parts with which it will eventually be used.
  • our molding process utilizes a rigid female mold 40, which is preferably made of steel for durability, and which is dimensioned to define the outer mold line (OML) of part 10, wherein side wall 42 forms the outer mold line for part panels 22 and 24, side wall 44 forms the outer mold line for part panels 26 and 28, and end walls 46 and 48 form the outer mold line for the end panels 14 and 16 of member 10.
  • Mold bottom wall 50 forms the outer mold line for bottom or floor panels 18 and 20 and includes a plurality of locator cones 52 which serve to loosely position the conformable cauls during the molding process as described hereinafter.
  • Conformable cauls will be utilized to perform the function of the flexible male mold in our molding process, and their fabrication will now be described.
  • an exact model of part 10 is made either of fiberglass, wood, or other available material that is capable of withstanding the desired heat and pressure necessary to vulcanize fluoroelastomer materials. That model is positioned in female mold 40, sometimes called the tool, for purposes of rigidity during the conformable caul fabrication process.
  • a conformable caul is to be formed for each of the composite part panels 12 through 20, or conceivably for portions of each. These conformable cauls, when fabricated, will cooperate to define the inner mold line (IML) of part 10.
  • a layer of separator release film is first placed on the surface of each of the aforementioned model panels, and the conformable cauls will be laid up individually, i.e., one at a time, on each of panels 12 through 20.
  • a layer of separator release film is positioned between each lay-up so that following lay-up curing, individual and discrete conformable cauls will have been formed for each of the panels 12 through 20.
  • a conformable caul will be fabricated for each side of panel or transverse bulkhead 12 since the opposite side of bulkhead 12, which is not shown in FIG. 1, is the mirror image of the side shown in FIG. 1.
  • the conformable cauls are made of fluoroelastomer and are preferably five ply.
  • the first ply is preferably a 0.032 inch ply of release coated fluoroelastomer.
  • the second ply is preferably a 0.030 inch ply of fluoroelastomer gum stock.
  • the third and fourth plies are a 0.040 inch ply of KEVLAR® reinforced fluoroelastomer, while the fifth ply is the same as the second ply, thereby giving a ply lay-up of 0.172 inches of reinforced fluoroelastomer for each of the conformable cauls.
  • the material for each of these plies can be obtained, for example, from the Minnesota, Mining & Manufacturing Company of Minneapolis, Minn.
  • a layer of separator release film is positioned between the lay-up on each panel member 12 through 20 so that, following curing, discrete and individual conformable cauls will be formed for each panel 12 through 20.
  • the entire unit With the individual cauls so laid up, and with the part model positioned within female mold 40, the entire unit is placed in a one-piece silicone bag and debulked and cured in an autoclave to produce individual conformable cauls for each of panels 12 through 20.
  • these conformable cauls it is important that they be fabricated so that, as best shown in FIG. 3, there are overlapping flanges 54 and 56 between adjacent cauls so that the conformable cauls, when under pressure during curing, will assume the precise shape of the female mold. This is particularly important at the corners where the various panel members meet since high strength and, hence, less flexible reinforcement members are used in the composite material in these areas.
  • part 10 is to be made of composite materials and by a molding process. While in our preferred embodiment, all lay-up of prepreg composite material will be made on the individual conformable cauls for each part 10 panel, it is possible and necessary if the prepreg material is to be continuous throughout the outer mold line of the part being fabricated 10 that a portion of it, the continuous portion at least, be laid up in the female mold as shown in FIG. 4.
  • a plurality of preimpregnated plies such as 58, 60, 66 and 68, are laid up along the inner surface of female mold 40, while the remainder of the preimpregnated plies of the composite material will be laid up individually on the various conformable cauls for each part panel 12 through 20.
  • the various plies such as 58 and 60, extend uninterrupted from the top surface 62 of wall 42 to the top surface 64 of wall panel 44.
  • plies such as 66 and 68 are continuous between the top surface 70 of wall 46 and the top surface 72 of wall 48, all for the purpose of added strength to the composite part 10 being fabricated.
  • FIG. 5 For a description of the lay-up of the prepreg composite material plies on the conformable cauls, reference will be made to FIG. 5.
  • a typical conformable caul 74 is positioned on rigid cradle 76, which is in the shape of caul 74, to provide it with complete rigidity.
  • the various plies of prepreg composite material, such as 78 and 80, are laid up thereon along the contoured surface thereof and will be laid up as necessary to have the prepreg composite ply lay-up on conformable caul 74 form the outer mold line of part 10 by itself or in cooperation with the previously laid-up plies in the female mold shown in FIG.
  • the opposite surface of the ply lay-up will define a portion of the inner mold line of part 10 in view of the shape of the conformable caul 74.
  • three layers of prepreg material such as woven graphite fabrics, are laid up directly against conformable caul 70, and then some eleven layers of prepreg reinforced composite material, such as continuous graphite prepreg and woven graphite fabrics are layered thereon, and finally three final layers of prepreg material, such as woven graphite fabrics, are laid over the eleven reinforcing layers. All of these fabrics are made by Narmco of Anaheim, Calif.
  • any strengthening members or details such as the NOMEX® cores 34, 35 and 36 shown in FIG. 1, or the reinforcing beads 30 shown therein, or the thermo plastic bonding substrate 37 shown therein, are required for the particular portion of the part 10 which will be fabricated utilizing the particular conformable caul 74 shown in FIG. 5, that part would be selectively positioned and included in the lay-up appropriately between the prepreg layers previously described.
  • the laid-up unit including rigid cradle 76, is placed on a conventional debulking table and subjected to vacuum so as to debulk the various prepreg ply layers so laid up to cause them to assume the shape of conformable caul 74 very exactly. Similar lay-ups are made on the conformable cauls for each of the panels 12 through 20 and debulked.
  • each can be placed in a cold environment to prevent curing of the prepreg plies until part 10 is to be fabricated, if necessary.
  • a removable flange member 51 may be used to assist in positioning the conformable cauls which form bulkhead 12.
  • Flange member 51 is selectively positioned by pin 53, which extends into mold boss 55, together with a corresponding pin and boss on the opposite side to extend between mold walls 42 and 44 at the proper location to properly position the more rigid of the two cauls which will form bulkhead 12.
  • Positioning cones, such as 52 may be used to position the bottom of the more rigid caul which will form bulkhead 12.
  • a one-piece silicone vacuum bag 86 is then placed over the entire unit as depicted in FIG. 6 and a vacuum applied thereto so as to place the conformable cauls in a pressurized condition with respect to the female mold so that the prepreg layers of composite material, which are going to eventually form the composite part 10, are debulked under pressure in the mold.
  • the mold in this vacuum bagged condition, with vacuum applied, is an autoclave ready unit which is then put into an autoclave 88 and cured.
  • the various lay-ups of prepreg material on the individual conformable cauls are co-cured to form a complex one-piece part made of composite material and having a plurality of panels oriented in diverse angular relationship, such as the one shown in FIG. 1. It will further be seen that in our molding process, the plurality of conformable cauls coact to form the male mold in our molding process.
  • a one-piece silicone bag is selected for use in our molding process because its one-piece construction conserves labor, and silicone is reversion resistant, i.e., it will assume its original shape following the molding process, the silicone bag is reusable and still further silicone is not attackable by the epoxy or other chemicals to which it may subjected during the curing process.
